Description

Be used to produce the method for stable boron-containing solution
Technical field
The present invention relates to be used to produce the method for solution with lubricating property.The present invention is specifically related to be used to produce the method for the solution with lubricating property, and said solution contains boron and preferred expection is used as fuel or lubricant additive.The present invention relates more specifically to produce the stable enriched material of dissolved boron, and when for example being used for machine or mover, said enriched material causes enhanced lubricated and the friction that reduces, the corrosion risk of reduction and the wearing and tearing of minimizing.The present invention also comprises according to the B solution of said method production and the purposes of this B solution.
Background of invention
Various types of lubricants are particularly useful for using machine part or engine parts Anywhere.Lubricant properties is good more, and the energy that machine consumed that then turns round is just more little, and the abrasion loss of building block is more little.For many years, have realized that alkaline matter boron has extraordinary antifriction characteristic.Experience test shows, through boron being mixed in lubricant and the fuel, can bring significant saving of fuel, if especially the granularity of boron substance is that the scope of 0.5-100 nanometer is when interior.Favourable lubrication is owing to the following ability of boron: form complicated co-ordination bond with metal, form the multidimensional plate thus, a little less than Van der Waals force between the said multidimensional plate, therefore said plate relative to each other slides easily.Boron substance forms the selfreparing system, and reason is the material that wears away with the lasting replacement of the new key of metal formation.In addition, borate ion is owing to their electronegativity constitutes counteracting or the efficient reductive agent of prevention corrosive.
Having carried out many trials is dissolved in boron in various liquid and the lubricant.Problem all the time is to produce water base B solution; The boron substance that wherein has expectation granularity and concentration is dissolved in the liquid and maintenance dissolving in time fully; Make boron substance not precipitate, and do not make liquid muddy or be deposited on the container bottom of ccontaining liquid/solution.
Therefore, through interpolation boron substance/compound boron being mixed in fuel or the lubricant is prior art.Several different methods is also granted patent.
For example, US6368369 (advanced lubrication technology) describes a kind of being used for boric acid is mixed the method with realization antifriction characteristic with for example motor spirit.This method relates to mixes boric acid with base oil, and the granularity of endeavouring to ensure boron is 0.5 to 20 micron, and this for example realizes through so-called jet grinding.
US6783561 (Foley and Lardner) especially mentions and a kind of boron is added to fuel or lubricant with the concentration of 30-3000ppm and makes the method for boron with " known way " and fuel or mix lubricant.About how realizing that actual mixing does not have further specify.
SE524898 (Eagle Water Ltd) described a kind of be used to produce as expection be used for the method with the B solution of liquid such as liquid fuel blended enriched material form.This method is equivalent to boron cpd and solvent and stirs and/or shake the gained mixture, can and can under the temperature that promotes, carry out by means of the segmentation element of machinery.Boron content can be up to 250000ppm, but preferred in the scope of 10-1000ppm.Blending means is not described in detail.
Therefore, prior art shows, boron is with " known way " and solvent, but do not point out how to realize following solution more in detail: have consoluet boron substance, and wherein boron substance keeps dissolving fully, thereby obtain stable in time solution.For example do not explain how initial boron material or grade or its are handled/mixed to be dissolved in the liquid fully and to keep dissolving stably in time.Further research is found, and the B solution through these currently known methods productions can not keep stable in time, and this is for can on market, to sell solution be important and maybe key a problem.Therefore, have been found that the dissolving stably that can not become of boron particles in the solution, but reunite easily and deposition gradually in time, especially cause liquid to become muddy.Boron particles also can progressively be deposited on the bottom of container (it possibly be the food tray of for example vehicle) of ccontaining solution.The boron content of liquid reduces expectation and the expection lubricating property that significantly reduces solution, and accumulative boron deposition even can cause damage to mover and machine.For example; If the deposition boron of aggregated forms gets into for example mover, it will be in whole mover, for example on piston, on the vent valve, in the pump, in the strainer and on other key part of mover or among form the harmful settling of the hard of not expecting.
Therefore, the state of the art does not point out how to solve the problem that obtains B solution not muddy and stable in time under granularity of expecting and concentration.
Summary of the invention
An object of the present invention is to address the above problem; And a kind of method of in background of invention, pointing out of B solution that obtains having expectation granularity and concentration proposed; Through this method, boron substance is dissolved in the liquid fully, and the B solution that obtains keeps stable in time; And when for example being used for machine or mover, on the composition mechanical part, cause friction, the corrosion risk of reduction and the wearing and tearing of minimizing of lubricating, reducing that increase.
Another object of the present invention be propose a kind of aspect preparation and acquisition and use simple and cheap method.
These with other purpose and advantage according to the present invention and the method for the characteristic of pointing out in the characteristic according to claim 1 be achieved.
Therefore, the present invention relates to be used to produce the B solution with good lubrication characteristic, said B solution is mainly expected as the additive of fuel or lubricant.The boron powder that said method relates to particular level mixes in a plurality of steps and with certain blending ratio with solvent.Mixture experiences mechanical stirring at least two steps, add other liquid, solvent at least between said two steps, during said stirring, can allow the temperature of mixture to raise.
Other features and advantages of the present invention are explained through the following more detailed description of enumerating of the present invention and accompanying drawing and other claim.

Embodiment
Therefore, the present invention relates to a kind of method,, the boron such as the boron cpd form is added to liquid and segments/be dissolved in the liquid, thereby make that boron substance keeps stably being dissolved in the liquid in time through this method.
For example, can use boron cpd such as crystallization boric acid, boron oxide, boron trioxide etc.Preferred use powder type contain oxygen boron cpd H 3BO 3Therefore, it is the white crystals boric acid of pharmacy quality, promptly has to be preferably at least 99% purity and the molecular weight of 61.8g/mol.A replacement scheme is to use water-free boron oxide B 2O 3, the molecular weight that it has 69.6g/mol is also referred to as anhydrous boric acid.Therefore boron oxide is not have the boric acid of water-content and can the mode identical with boric acid use.Boron oxide water (like water of condensation) spontaneously changes into boric acid.
Treat to be preferably organic and/or inorganic liquid or gas with boron substance or boron powder blended liquid.The instance of this class I liquid I is kerosene, petroleum naphtha, water, vegetables oil/synthetic oil/oil, alcohol.The instance of suitable gas is methane, hydrogen etc.Amount of liquid can be short run, for example about 3 liters, but also can be for example about 1000 liters/batches.
It is important using/obtain the boron particles with small grain size.Be used as on the boron particles size of initial feed in initial scope from 1 millimeter to 10 micrometer ranges.
During mixing make the boron particles band bear static electric charge also advantageously.If select alcohol as solvent, then its hydrogen bond will be offset the electronegativity of boron cpd, and therefore offset latter's inherent covalent bonding tendency.Boron particles can stir to be with through brute force bears static electric charge, and as by means of blender blade etc., blade can preferably have aerofoil profile, twist and be furnished with winglet in this case.
The mixing tank method
In the method, boron substance with comprise two key steps mixing of liquid, at least one step, use mixing tank.The structure of blender blade need make and between their upside and downside, have big pressure reduction.Their profile needs blunt leading edge and sharper trailing edge, and blade setting need be for 0.5 to about 3 degree, preferred about 2 degree.Said setting is suitable for reaching the input angle of striding more uniformly through the surface, and reason is how far to locate to run into liquid and blended particle with it according to blade at the distance center line, and blade profile moves through liquid with different speed.Optimal blade has the profile that the permission laminar flow crossed and passed the thick (that is, 20% (like what from the leading edge of profile measure) of profile greater than chord length) of profile chord length.Profile comparatively sharp distal causes liquid and particle thereof to be brought to together/to mix with different rates.The conforming blade profile that can get on the market can be Clark Y TM, NACA-6 TMSeries or SG6042 TMProfile has low Reynolds number and thickness is that about 12% of chord length is important.The viscosity influence of the certain liquid body of mobile character.The used time of the net result that obtains expecting will be depended on blade structure.The trickleest boron particles through with liquid in the mutual wearing and tearing and the collision of other boron particles obtain.This collision is most of to be taken place at the trailing edge place that liquid/particle meets at a high speed.
A step that is used to obtain to stablize B solution is to use the boron substance (method steps 1) with some particular characteristics.The selection of boron substance influences net result greatly.The boron substance that satisfies this method requirement is powder type and the borax H with pharmacy quality 3BO 3, promptly have the boron substance of the molecular weight that is preferably at least 99% purity and 69.6.Boron oxide B 2O 3(being also referred to as anhydrous boric acid, promptly water-free boric acid) also is available.
Another step is to select wherein to wait to mix the liquid or the solvent (method steps 2) of boron substance or boron powder.This liquid is preferably organic and/or inorganic liquid or gas.The instance of the liquid that can expect is kerosene, petroleum naphtha, water, vegetables oil/synthetic oil/oil, alcohol, and the instance of the gas that can expect is methane, hydrogen etc.
Another step is to use pre-mixed between boron powder and the liquid than (method steps 3).This is to be used to obtain the key factor according to product of the present invention.Ratio of mixture need be about to about 4 parts boron and mix with 100 parts liquid/solvent by weight being about 1 to 25.Certainly, ratio can varied somewhat, for example depends on the temperature of solution when mixing, but also depends on which kind of solution of final expection.If the solution expection is used for the application of diesel oil fuel, then adopt about 1/1000 ratio of mixture.
Following step is component to be mixed each other (method steps 4), and treating mixt/solution mechanically, as in being furnished with the mixing tank of blade, carrying out.Mixing tank is so that at a high speed (that is, about 15, the initial predetermined amount of time that 000rpm) stirred the mixture 15-20 minute obtains initial soln (method steps 5).In this stage, the temperature of solution possibly rise, but must never surpass disassociation (breakdown) point of solvent (for example oil).Therefore, initial mixing occurs in the low-viscosity (mobile) liquid that mainly comprises charged particle not, and causes the boron particles of micron-scale.Mixing was carried out 15-20 minute with about 800km/ hour blade rim vdocity, and produced the temperature rising from 20 ℃ normal room temperature to about 50-60 ℃.Mix preferably and under barometric point, take place.After this, add other liquid (for example oil) (method steps 6).
Following step is to make the other second about 15 minutes predetermined amount of time (method steps 7) of mixing tank operation.Allow the temperature of solution to rise, but do not reach the dissociation temperature of liquid.If use oil, then temperature should be above 80 ℃.The particle of nano-scale takes place and generates in this second mixing (it causes the finished product) thus in the liquid of viscosity higher, and makes particle charged.Mixing takes place with about 800km/ hour rim vdocity, and carries out 30-40 minute, in this time, causes temperature to rise to about 70-80 ℃.Be blended under the barometric point and take place.The rim vdocity of blade should be 500 to 800km/ hours.Lower speed causes magnetism between long mixing time and bigger particle, and the result causes more the finished product sedimentation and gathering.
The temperature of liquid can be-25 ℃ to+75 ° when mixing beginning.Initial temperature is to net result and/or almost not influence of mixing time.
Temperature is owing to the kinetic energy that is developed rises between mixing period.Begin to form crystal at 170 ℃ of boric acid, destroy solution thus.Mention that like preamble mixing the temperature that reaches when accomplishing should be above 80 ℃.
Afterwards, add other liquid (method steps 8), and further mixing solutions, such as 10-15 minute.The amount of mixing the liquid in the solution is to make final use mixture (promptly from ultimate customers mixes additive the motor spirit of expectation, obtaining) show to use the concentration of about 20-30ppm in the mixture (like, motor spirit).
After greater than the existing chance sedimentation of the particle of 100 nanometers (method steps 9), the finished product are retracted to (method steps 10) in the suitable containers.
The method of rolling
First step that obtains stablizing B solution with this method is to use the boron substance (method steps 11) with particular characteristics.The selection of boron substance significantly influences net result.Boron cpd for example can be made up of crystallization boric acid, boron oxide, boron trioxide etc.Preferred use powder type contain oxygen boron cpd H 3BO 3Therefore, it is the white crystals boric acid of pharmacy quality (that is, have be preferably at least 99% purity and the molecular weight of 61.8g/mol).A replacement scheme is to use water-free boron oxide B 2O 3, the molecular weight that it has 69.6g/mol is also referred to as anhydrous boric acid.Boron oxide is not have the boric acid of water-content and can the mode identical with boric acid use.Boron oxide water (like water of condensation) spontaneously is converted into boric acid.
Following step is to select and use the liquid/solvent (method steps 12) of wherein waiting to mix boron substance or boron powder.Under this situation, select to have by volume at least 95%, preferred 99.5% or higher alcohol.Liquid also can be organic and/or inorganic liquid or gas.The instance of the liquid that can expect is kerosene, petroleum naphtha, water, vegetables oil/synthetic oil/oil.The instance of the gas that can expect is methane, hydrogen etc.
Following step is to use certain ratio of mixture, said ratio of mixture be chosen as in the method to every liter of liquid use 0 to 300g, the preferred boron substance of about 20-30g (method steps 13).Ratio of mixture depends on the final purpose that mixture is to be used.The oil that higher concentration expection is used for not consuming at for example mover or chain etc. is used additive, and oil/fuel that lower ratio of mixture is used to be consumed, like two stroke oil fuel.
Following step is that mixture is rolled, is about to it and puts into and be furnished with interior panelling or hold steel ball or the rotating cylinder of similar mixed organization, and the initial predetermined amount of time (method steps 14) that rotates preferred 8-10 hour with the speed that is suitable for purpose such as 2-10rpm.The program of rolling is preferably carried out in room temperature, still, can certainly carry out in other temperature, for example carries out in the temperature that improves.
Afterwards, adding other liquid is thinner (method steps 15), and its amount is mixed concentration that the final use mixture that in separately motor spirit reach show about 20-30pp according to mixing explanation with additive through ultimate customers for making.Be further to mix second predetermined amount of time (method steps 16) after this step.
Afterwards, for example separate boron particles, promptly greater than those (method stepss 17) of 100nm with volume particle size through sedimentation.
Afterwards, be that the finished product/additive is retracted to (method steps 18) in suitable containers such as the Plastic Bottle with solution.Ultimate customers will be subsequently according to mixing explanation, preferably, additive is added in the motor spirit separately with 1 to 1000 ratio, cause in the motor spirit the preferably final boron concentration of about 20-30ppm.
Therefore; B solution mixes in the for example basic liquid; Produce enriched material or additive thus, it dilutes in other liquid for application target, preferably at propelling agent such as various forms of gasoline; For example dilution among alkynylene, avgas 100LL, the avgas 91/96 possibly mixed various alcohol, methane etc.Propelling agent also can be various forms of diesel-fuels, for example diesel oil, combined diesel oil fuel, RME, REE, FT diesel oil fuel, kerosene, petroleum naphtha etc.Other liquid also can be various forms of water, for example steam, or vegetables oil/synthetic oil/oil.Multiple gases also can expect, for example hydrogen, liquid hydrogen etc.
The boron concentration of enriched material/additive can be for example high to 250000ppm or more.After adding additive, the finished product fuel mixture should reach in the 10-10000ppm scope, the interior boron content of preferred 20-30ppm scope.Higher concentration, promptly high to 10,000ppm mainly is suitable for use in the pure lubricant.
Also can be advantageously utilised in for example corrosion protection/lubricated spraying or the grocery trade application according to B solution of the present invention, and need not protect classification.B solution also can be used as mold oil, and for example when boning with sliding form frame, or as cutting fluid, wherein boron cpd also will have anti-microbial effect.Solution also can serve as the oil-free lubricatoin agent of metal stamping industry, makes to eliminate punching course recovery of oil afterwards.
Solution/additive can certainly be directly or indirectly as the lubricant in organic and/or inorganic liquid and the gas, it also can reduce costliness and amount that environment had more multicontaminated product.
Purposes in used for vehicle fuel reaches additional advantage, i.e. more effectively lubricating pump, nozzle etc.
Fig. 3 describes to be used to utilize the device 19 of boron substance treatment liq from the top.A plurality of nozzle 21a-c, metal sheet 22, supply-pipe 23 and collection channel 24 are arranged in the treatment chamber 20 of base closed.B solution under the pressure supplies to treatment chamber 20 so that B solution is sprayed on the liquid through nozzle 21a-c.Nozzle 21a-c is therefore towards metal sheet 22.Untreated liquid (for example oil) supplies to treatment chamber 20 and metal sheet 22 through supply-pipe 23, and is distributed in the supply-pipe 23 through hole 25.Oil or liquid are evenly distributed on the metal sheet 22 of inclination, and are downward through the metal sheet 22 of inclination towards collection channel 24.The angle flow velocity of the metal sheet 22 of the oil that gets into or the pressure of liquid and inclination, and therefore influence exposure duration from nozzle 21a-c spraying.This device can be used for the liquid of number of different types.
